Understanding Your T-Mobile Rate Plan
Choosing the right T-Mobile plan involves more than just picking the cheapest option. With the introduction of the Go5G suite, T-Mobile has shifted focus toward "New In Two" and "New In One" upgrade cycles. This calculator helps you estimate your monthly service costs based on current retail pricing structures.
Plan Comparison: Go5G Next vs. Go5G Plus
The primary difference between T-Mobile's top-tier plans lies in how often you can upgrade your device. Go5G Next includes the cost of upgrading every single year (once 50% of the device is paid off), whereas Go5G Plus aligns with standard 24-month financing cycles while still offering the same "new and existing customer" promotional deals.

Pricing Examples
Single Line Users
A single line on Go5G Plus typically costs $90/month with AutoPay. For those looking to save, the Essentials Saver plan starts as low as $50-$60, though it lacks the premium data and international perks of the Go5G series.
The Family Plan "Sweet Spot"
T-Mobile frequently offers a "3rd Line Free" promotion for new accounts. This significantly lowers the average cost per line. For example, 3 lines on Go5G Plus with the promotion costs the same as 2 lines ($150 total), bringing the per-line cost down to $50.
How AutoPay Impacts Your Bill
T-Mobile provides a $5 discount per line for users who set up AutoPay using a debit card or bank account. Note that as of 2023, credit cards no longer qualify for the AutoPay discount. This discount applies to the first 8 lines on a consumer account, offering a maximum savings of $40 per month.
